The ACCC issued a Consultation Paper seeking submissions on Viterra's revised proposed auction system for the use of its port services for bulk wheat export.

The ACCC accepted an Access Undertaking in September 2011 which required Viterra to replace its first in, first served capacity allocation system with an auction system.  The initial proposed auction system was rejected by the ACCC.  In an attempt to address the ACCC's concerns (as outlined in the Auction Objection Notice), Viterra's revised proposal includes changes aimed to allow for the auctions to conclude more quickly and to prevent gaming.
